The project will involve the study of stains on fabrics and the factors influencing their removal. Some commons household materials, for example tea, can cause stains on fabric that are very persistent and hard to remove using existing wash formulations. An additional complication in this work is that although these stains can be readily removed when fresh, under certain conditions they age to form persistent and intractable deposits that are much more challenging. This project will study the interactions of molecules present in these stains with the fabric substrate, and look at the effects of other species, for example metal ions, upon their behaviour and persistence. The study will include the use of non-contact spectroscopic methods for the analysis of the materials and extend this to the study of fabrics under wash conditions.

该项目将涉及对织物的污渍的研究以及影响其去除的因素。一些公共材料（例如茶）可能会导致织物上的污渍，这些污渍非常持久，并且很难使用现有的洗涤配方清除。这项工作的另一个并发症是，尽管新鲜时可以很容易地去除这些污渍，但在某些条件下它们会形成持久且顽固的沉积物，这些沉积物更具挑战性。该项目将研究这些污渍中存在的分子与织物底物的相互作用，并查看其他物种（例如金属离子）对其行为和持久性的影响。该研究将包括使用非接触光谱方法对材料进行分析，并将其扩展到清洗条件下的织物研究。
